i have 2 drop down list on my web page
-the first one bound to a sqldatasource and it's work fine
-the second one bound to a sqldatasource (with a parameter depends on the first drop down list selected value )and it's work fine too .
But when a user make a selection on the second drop down list, any post back on the page will return the second drop down list selected index equal to 0.I tried so hard (ON MSDN) to understand why this happen only on this drop down list.
Extension to my previous question http://bit.ly/c5yiVM
I have 7 textboxes. If Top 1 textbox(Volume All Years) text changed, text need to be updated in next 6 inputboxes(Latest 2009 Volume to Latest 2014 Volume). I need javascript or Jquery for this. I will write Js textchanged() or focuschange() for top 1 textbox. So what should I write in focuschage() or textchanged methods().
I changed little bit in code. Now Html will like below. These textboxes have common CssClass. volumetextbox. Can we use this class and change text in all textboxes those have same CssClass.

I'm programatically looking ito a .aspx file and getting the file class name declared in its CodeBehind. For example, when analyzing myFile.aspx I read in its Page Directive and found its CodeBehind equals "myApplicationmyPage.aspx.vb". Then I use the code
below:
[Code]....
Now I want to read the BaseFile (class = myApplication.Forms.BasePage). However, to read in this file, I need I need to get its full path instead of its namespace.class hiearchy. In this case, the BasePage is wrapped in a different namespace declaration thus I cannot just change the '.' to '' in order to get the path.How can I get the path of BasePage so I can read it?
i have the same prblmi have a class file in app_code/fol1/fol2/class1.vbbut when i call it as dim x as new class1 i am not getting itshld the class file be placed in app_code folder or outsideactually i had creatd the namespace but i am not able to import i
View 8 RepliesWhen you add a Web Reference in an ASP.NET project in Visual Studio the web application's root namespace is always added.So, if I add a web reference called MyWebService and the default namespace of the application is MyApplication the namespace of the generated proxy class will be: MyApplication.MyWebService.
However, I want to be able to specify which namespace to use for the generated class (to skip the default namespace and have the namespace be called simply MyWebService).Is using wsdl.exe through the command line the only way of accomplishing this? I don't want to manually edit the generated class (since it can get re-generated).
I have added global.asax file in my webservice project. in webservice project i have one class file name as 'Class1.vb' in this class contain some methods() , i want to access those methods from 'class1.vb' in global.asax.vb file. any body knows how to access those methods in global.asax.vb. file
View 5 RepliesI am relatively new to asp.net environment.Recently working on a project, i discovered a problemi.e. I had to add using system.io to all file functions in any page. same for using sql functionsi.e. any method for that namespace had to be used in full like By adding the following section in web.config , ALL my pages automatically have access to that namespace
<namespaces>
<add namespace="System.Data"/>
<add namespace="System.Data.SqlClient"/>
<add namespace= "MySql.Data.MySqlClient"/>
<add namespace="System.IO"/>
</namespaces>

Currently, I have many controls and objects such as Chart1 of mschart as part of the public partial class _Default : System.Web.UI.Page.
At the bottom, I've created a second class that is not part of the _Default webform class. How can I access the webform controls from this second class?
For example, I want to do
Chart1.Series["Series1"].Points.AddXY((pointIndex + 1) * 40, datapoints[pointIndex]);
I want to pass pointIndex integer and the datapoints array.
I know that Chart1 was created protected global access modifier in the designer.cs but when I changed it to public, it still had a problem.
I've created a new class in App_Code
namespace Site {
public class MyClass {
public MyClass() {
}
}
}
this is my Global.asax.cs
[code]....
The error is in: MyClass myClass = new MyClass();
The type or namespace name 'MyClass' could not be found (are you missing a using directive or an assembly reference?)
I create a database with more than 10 tables, how can I automatically generate business object class inside asp.net C# project?
I hope that one expert can give me steps for how to do that?
I would like to generate my links automatically via a static class in each of my aspx pages (or in a common BasePage).Currently I use this:
private const string TEMPLATE =
"~/One.aspx";
public static string Link ()
(
string link = String.Format(TEMPLATE);
return link;
)
But the name of my page, One.aspx is hardcoded. Is it possible to generate the path instead of this hardcoded constant TEMPLATE. You should know that I do not instantiate the class before creating the link.
I have created an extended method for DataTable. I want to generate a class automatically in my solution when i call that method while writing a code as Visual studio does when it doesnt find the method.e.g mytable.mymethod(); Generate a class
View 2 RepliesI'm new to this forum, Ok here is the problem. I tried to implement the user profile pattern that provided by ASP.Net 2.0, first I added this couple of tags to the web.config
<system.web>
<anonymousIdentification
enabled="true"/>
<profile>
<properties>
<add
name="Name"
allowAnonymous="true"/>
<add
name="Age"
allowAnonymous="true"
type="System.Int16"/>
<group
name="User">
<add
name="Category"
allowAnonymous="true"/>
<add
name="MemberSince"
allowAnonymous="true"
type="System.DateTime"/>
<group>
<properties>
<profile>
Then I buit the project and moved to the page code behind, the surpise is that I didn't have the Profile object in the intellisense.
Web Application Project Has project reference to Class Library 1 in same Visual Studio 2008 solution Class Library 1 Has project reference to Class Library 2 in same solution Class Library 2 Has a file marked as Build Action: Embedded Resource and Copy to Output Directory: Copy Always
When I build my Web Application Project, the embedded resource in Class Library 2 is NOT copied to the bin directory of the Web Application Project as it should. If I add a project reference directly from my Web Application Project to Class Library 2, the file IS copied to the bin directory. How can I get the embedded resource file to copy without having to add the unnecessary reference?
When I move some web-based code from VS2008 to VS2010, I find it is different when it is hard to handle the Image class.
Let's take the following code as an example.
[Code]....
As I have already imported the System.Drawing namespace, I still cannot use Image.FromFile method as VS2010 detectss the Image class is in System.Web.UI.WebControls namespace.I have lots of such a kind of code in my project using Image class and I will get messed if need to modify the code from

Since I also used image in my variable name.

View 3 RepliesI'm using MonoDevelop on Mac OS X Snow Leopard to develop an ASP.NET MVC Application. I have tested it on Visual Studio 2008 on Windows 7 and it worked fine, but when compiling it on MonoDevelop it throws the error: The type or namespace name 'Objects' does not exist in the namespace 'System.Data' under this line: public partial class MoviesDBEntities : global::System.Data.Objects.ObjectContext
View 1 RepliesI use vs2008 and my MVC 1.0 and 2.0 Projects were working perfectly but all of a sudden i have an error on trying to compile all of them;
The error is of the form;
Error 1 The type or namespace name 'Controllers' does not exist in the namespace 'XXX' (are you missing an assembly reference?)
Error 3 The type or namespace name 'Models' does not exist in the namespace 'XXX' (are you missing an assembly reference?)
Error 4 The type or namespace name 'AccountController' could not be found (are you missing a using directive or an assembly reference?)
Error 5 The type or namespace name 'IFormsAuthenticationService' could not be found (are you missing a using directive or an assembly reference?)
Error 6 The type or namespace name 'IMembershipService' could not be found (are you missing a using directive or an assembly reference?)
These errors seem to come from the HomeControllerTest and the AccountControllerTest.
note that i recently installed Azure Tools using the Web Installer..Dunno if that could be the cause or problem.
when I put a break point i get this error message:
